Abstract

Exploring the interactions between compulsive buying and dietary practices is crucial in terms of understanding these behaviors from a behavioral standpoint. This paper investigates the relationships between compulsive buying (CB) and non-compulsive buying (non-CB), focusing on the influence of dietary habits (TFEQ), body mass index (BMI), and emotional valence. The study involved a representative sample of 707 Polish adults and employed tools such as the Compulsive Buying Scale, the Three-Factor Eating Questionnaire (TFEQ), and the Emotional Appetite Questionnaire (EMAQ). The results revealed that compulsive buyers (CBs) had higher levels of cognitive restraint, emotional eating, and uncontrolled eating than non-compulsive buyers (non-CBs). Importantly, emotional valence—which includes both positive and negative emotions—significantly influenced dietary behaviors, illustrating the complex role emotions play in food consumption. Additionally, the results highlighted that the BMI significantly affects these relationships, suggesting different eating patterns across BMI categories. This study underscores the need for targeted interventions focusing on psychological and nutritional aspects to address these interconnected compulsive behaviors.
